I have Headplay they are big and gooffy and only weight 400g. You need a HDMI output on your RC, They are HD and the image is very good and on a 7 inche screen. They give a feeling of being behind a huge windshield in the sky, the image is large and you have to look around, for me great for flying and they would be too big for racing. The advantage is that you still have your tablet for Go and can change settings. All the telemetry of GO is on the screen in the Headplay, no map. For me these are perfect and you can take your familly and friends for a ride.
